I have a leveling kit and run 275/60/20, which are a 33-inch tire with no rub.

Yes gained about 1.5mpg with CAI and TBS

what kinda throttle body spacer did you get im looking into one. actually i really am looking into making my truck rev faster when you hit the gas in neutral or park, it takes it good ole time reving up

What about a 305/70 17? I noticed that a guy at work has a 2 inch leveling kit on his silverado with 295/70 17's on it, but BFG does not make a 295/70 17. The closest is 305/70. Do you think that would work, or would that be too big for a stock rim?

I have a 2in leveling kit on my 08 4x4 and have had 325 60 18 nitto grapplers for 40k miles. Slight rub on full flex but doesn't bother me or the truck. These are roughly 33.2 inches tall by 13.3 inch wide and I get tons of positive press by others who see the truck. About to buy new grapplers and considering 35 x12.5, gaining a little height by giving up a little width. May call for a bit of wheel well trimming. Anyone tried this size tire in this application before?

If 33s are rubbing there is no way you're going to fit 35s without adding a lift.

hey everybody, I just got a 2012 sierra body color all terrain with the OEM 20's. I had a 2.25 leveling kit installed and I'm trying to see how big I can go on these stock wheels without rubbing. would like to run a 305/55/20 but afraid they wont fit. anybody run a set up like this and know what will fit?
